तुल्यवर्णच्छदः कृष्णः कोकिलैः सह संगतः ।
केन व्याख्यायते काकः स्वयं यदि भाषते ॥
tulya varNacChadaH kRuShNaH kokilaH saha sangataH ।
kena vyAkhyAyate kAkaH svayam yadi bhAShate ॥
A Crow can mingle with nightingales since they have the same plumage – black. No one will notice the difference until the crow starts to speak by itself. Only a fool would speak and reveal his ignorance in a congregation of wise men.
